The thing they remember the most about the People they hire to install, sell, and program their new investment (AV system) is how easy it is to work. That is the Key. That's "what" 9the programming), is gonna give you all the referrals. The only other thing the customer will remember is if you drill a water pipe with a drill bit. But I hope non of us have ever done that.
